DIASTEREOSELECTIVE ADDITION OF THE 2-PHENYLSULFONYL-SUBSTITUTED ALLYLIC BROMIDES TO ALDEHYDES IN THE PRESENCE OF ZINC OR CHROMIUM (II) CHLORIDE
Auvray, P.,Knochel, P.,Normant, J. F.
, p. 5091 - 5094 (2007/10/02)
The 2-phenylsulfonyl allylic bromides 1 add diastereoselectively to various aldehydes 3 in the presence of zinc or of in situ generated chromium (II) salts to give mainly the syn-hydroxy sulfones 4 in high yields.The sulfone 4b can be easily transformed i
